When the key is turned, my fuel pump relay starts clicking. I went to the junk yard and got a PCM from a 2000 ford ranger with the same motor now my truck will run with that PCM but theirs a new problem because when driving it hesitates if you push the pedal all the way down (most of the time) and its giving me transmission codes like my truck has an automatic trans in it but mine is a manual. Now I ordered a new PCM from autozone and the new one does the same thing as the original. Not sure if this is a wiring problem or a PCM problem thanks for any help.
